T all whom it moy concern:

- Beit known-thail, Uxms T, .Hlolrn a,

citizen of the. U ed States, residing at Candor, in the coun-ty'cf Montgomery, State of North Carolina, have invented certain new and useful improvements inv Pea-Hull` ers; and I do hereby declare Vthe following to be a full, clear, and exact description of the invention, such as ivillenablefothers skilled in the art to which it appertains to make and vuse,the same. Y

This invention lrelates to improvements in pea hullers andtlfreshers and particularly to a retlueshinf;r device. Y

The principal ob]ect of the invention is to provide an improved construction and arrangement of the jparts `whereby the 'peasare better threshed than in devices heretofore.

Other objects andladvantages will be apparent from the following description .and with particular reference to ing. drawings.

in the drawings: Figure l. isa side eleva- `tion of a threshingr machine made in accordance with my invention, Fig. 2 isa top plan View thcreof,'Fig,. .'3 is 'an end elevation taken from the cylinder end of the machine,"

Fig. f'l is an end elevation taken from the' op- .posite side, Fig. h isa; central Vertical longitudinal. sectional view through the machine, Fimo is a vertical transverse sectional view on the line 6-6 of Fig. 5. Referring particularly tothe accompanying drawings-, 1G represent-s a housing, inv

one ond of which is. mounted a toothed cylinder ll and a toothed concave l2. On top of the housing l() is a hopper li into'which thc peas :irc lu-ld and which arc fed from the cnil of the hoard H to the cylinder and to the coiwavc. 1Within the housing, and just h'elow ihe cylinder ll is an upwardly inlined guard l5 over which the peas, which have passed between the cylinder and lcon-- cavo., travel, and arc deposited on the npwardly and rearwardly inclined `screen i6 over which is .mounted tho conveyor .belt l7. The roar cud of' the screen. lf3 terminates a short' distance from the housing l0, the uppci portion of said rearend of the housing heing open as indi-'rated al. i8. The mosh of this screen is .of such .si-ze that the peas. will "-'il thier-"illrf'uiffh at sonioprint in their uprd ravvl. ifi ille ion-'rr part :di the rear ihr housing l!) is anotlur' lncinod guai'l V' l.'\. lau' slightly ,greater in size than g i.'- :he upper cud of the Iguard ifi the accompanyi."

- being dispo-sed .a short distance from the rear end of the screen* 16." The peas which have been carried b the'convey'er belt. 17 'drop' o the rear en of the screen'l onto the inclined guard 19, which ..guard'di rects1 Vthem into the chiite or spout arranged at the rear of the housinv.- The bottom of the said chute or spenta-20 downwardly .and transversely inclined which directs the peas -to the lower 'end of the inclined conveyer 21, the upper end o f which terminates over the chute 14 so that the peas which pass into this conveyer are redepos'itedbetween the cylinder and concave, thus vproviding that they he ret-hreshcd. i

, Av transverse shaft 23 extends through ,'tlie housing, and; has on its ends the belt' wheels 24 and 25g-which drive the cylinder Aby lmeans of the bclt26, asmaller belt'wheel 27. being.. arranged on the same shaft and oli theA same side 'of the machine -an'd comnlnnicating motion' to th'eonveyer. 2l. by means of the belt-28, the belt wheel be.- on the same shaft and of the same diamdeter but on opposite side ofthemachine -and on the same side as the conveyer 21.

In the forward end of the housingiswfan .casing 3G, in which is mounted -a blast fan,

3l. Atthe rear f4 the fan casing 30 is formed the nozzle 3.2 which directs the blast of air. against thefforward inclined surface 33' of the guard 19 lso that' said airv will pass np between the said -guard and screen 1G. As the nnhulled ends of the peas and chaff drop from the rear end of the screen 16,. the blast of air will blow' the chaff through the opcnirrgy 1S while the peas, hc-

ing heavier than the chaff, will drop 'on' to the. guard lf.) and lie conveyed .hack to the'cyliudcr. The peasnhich drop through the screen 16, .falhthrough thespout 32', into'a receptacle placed thereunder, this spout being'arrangcd in the bottom ot'the housing at thc lowcr end of thc guard 33', By this arra igcinc'nt the blast of. air is direct-cd upwardly and rearwardly and positively insures that thc. chaff will be blown f'rog'n the housing, and danger of the saule cuthring).r *again* with thc matcl'izd being bhrcshcd isi-duced toA a ufiuiuuun.

325. arranged parallel to cach other und passing over the rollers 34. across from one heit to the other, aud culvd thor-ciu. .uilu. regularly spun-.cd .strips fifi. nach of whirl; carries a .series of .Extending i ino outwardly extending ral-:e teeth ei pins 3?.

These relies engage enel Cfuiy the peas, tht.V have passed between the cylinder and concave, up the inclined screen 16.

ln the side of the fen casing is formed an opening-37, and pivotally mounted on the casing, and adapted to be moved over tlie opening to regulate 4 the amount of air which passes into the fan casing is a gate 38. On the pivot bolt'of the gate is a thumb screw by meaivns`- of which the gatemay be held in any position.

Onsaid transverse shaft 23 is a toothed .sprocket 39:1nd an endless chain belt 40 for communicating motion to the conveyer I?. The Atransverse shaft AO' extending v through the cylinder has on one end a 'small wardly inel'ining conveyer Within `the housing, a. screen below the eonveyer, Said screen terminating adgeeeglt the fm1- pnd of the housing, the rear endb the '-f ving an openin f. of the sang Screen, of down'wei'ail n outwardly inclined guard. Well from a point forwardly of and beio rear end of jle said screen to the lower of Suid opening, a guard wall downwediy and forwardly inclined from the innein enel of tbe lastmentioned guard w ll, the sziir walls at their point of. connection being spaced from the screen inwariy of tne Said end of the screen, and a blast fan hav'- ing' a nozzle disposed to ldirect the blast of air against lie lower portion of the downwardly and forwardly inclined guard Wall,

the disehafge end of tbe conveyor being so disposed with-relation to the laf mentioned guaso. wall that. sind eonvever will dif naig'e the partiallythreSb-efl material beyond lie upper ends of the guard walls and aeoes vthe current. of air :which issues from the upper end of the space between the sereen and the downwardly and forwardly inclined Wall.
